-This invention .relates Yto the manufacture of electric floor or table lamps, and'more'pan ticularly to improvements in theV construction and general varrangement of the base or 5 stand therefor. f j Practically all electric lamps of the kfloor or table type and with which thisinvention isy primarily concerned are provided with a vertically extending standard or pedestal i@ and a base uponwhich said standard or pedestal is supported. Ordinarily this base is of relativelygreat transverse dimension with respect to that of the pedestal or standard whose length varies in accordance with the 'style of lamp. This construction, involving a wide and often bulky base and a slender and more or less long standard or pedestal, makes the shipment and storage of the` lamps a particularly difficult and expensive probf Heretoforeand 'prior to this invention, various attemptshave been made from time to time to overcome the diiiiculties involved in shipping and storing lamp stands the bases and pedestals of which were'shipped and stored in assembled relation. In some cases the lamp standard has been constructed of separable parts necessitating the use of separable electric connectors where each part i0 was wired at the place of manufacture or necessitating wiring of the lamp after it had been assembled by the ultimate consignee thereof. Obviously, the employment of auxiliaryl electrical connectors within the lamp standard to effectl the necessary electrical conncctionlbetween'- the wired separable parts thereof increased ,the manufacturing cost of the lamp. On the other hand, where the sepe arable `parts oftlielamp standard were not initially wired'and supplied with electrical connectors special skill and care as well as time and laborwere ,required on the ipart'of the consignee to wire the lampV after he had assembled the several partsas received from the manufacturer. i 'n Y Among the objects ofthe. present invention is to provide a construction wherein the lamp standard or pedestal isA separable from the base thereof and wherebyall of the aforementioned diiicultiesrand objections'fmay be i obviated.l

provision of a lamp stand the'base of which is separable from the pedestal or standard thereof whereby to reduce to a minimum the expense of` shipping and storing these parts of the lamp stand. l

- A still further object of the invention is-the provision in a` lamp of a pedestal or stand- :A- further object of the invention is the ard therefor which is adapted for separable 6 securement to the base of the lamp, the pedestal being further characterized in that it is adapted to be completely wired by the manufacturer thereof preliminarily the same upon its base.

. vStill another and more specific obj ect of the invention is the provision of means for de-V tachably securing together a lamp pedestal or standardand a base therefor, the latter member being provided witha central opening the vertical axis of which is substantially coincident with that of the pedestal orstandard and of a diameter suhicient to permit the to mounting m free passage therethrough of an electric plug with which the pedestal or standard is equipped at the place of manufacture thereof.

Further objects of the invention are to provide Aa rigid and secure connection beL tween the separable lamp standard or pedestal and the supporting base therefor, to decrease the cost of manufacturing these parts, to increase the 'ease with which these parts may be assembled and.V- to provide va lamp stand which approaches, in external appearance those stands lwherein the pedestal and ybase are 'formed integrally, yFurther obgects and advantages of the invention! will appear more fully hereinafter. 'f

The invention consists substantially in the combination, construction, location and rela-v tive arrangement of parts, all as will appear more clearly from the detailed description to follow, as shown.` in the accompanying drawing and as finally pointed out in the appended claims.

In^the accompanying drawing, which is for the purpose yof illustrating certain preferred embodiments of the presenty invenl Figure 1 is a vertical sectional view of a lamp stand constructed in accordance with the principles of the present invention;

Figure 2 is a view taken on the line 2-2 of Figure 1;

Figure 3 is a bottom plan view of the arrangement shown in Figure 1; and

Figure 4 is a bottom plan view of a modified arrangement embodying the principles of the present invention.

Referring now to the drawing and more particularly to Figures 1 to 3 thereof it will be observed that the lamp stand as constructed in accordance with this invention comprises a base 10`and a vertically extending pedestal or standard designated by the reference numeral 11. The base 10, it will be noted, is of a transverse dimension which is relatively great with respect to that of the pedestal or standard 11, the length of the i latter varying in accordance with the particular style of lamp.

The base 10 is provided in the top surface thereof with a central aperture or opening 12 the vertical axis of which is substantially coincident with that of the standard or pedestal 11. Extending radially inwardly from the wall-13 of the opening 12 are a plurality of circumferentially spaced integrally formed lugs or bosses 14, the upper surfaces of which lie in a plane which parallels and is spaced downwardly from the horizontally extending plane of the top surface 17 of the base member 10. There is thus provided a depressed seat within the top of the base for supporting` the lower end of the lamp pedestal or standard 11.

Arranged to be received within this depressed seat is a member 15 of generally tubular form,the lower end of which is flared to provide an outwardly and radially extending fla-nge 16,. This flange is adapted to rest upon the lugs or bosses 14 provided in the base 10 and is so designed that the upper surf face of the flange 16 thereof lies substantially in the plane of the top surface 17 of the base 10. In other words, when the member 15 is supported upon the lugs or bosses 14 of the base inthe manner shown in Figure 1 the top surface of the flange 16 is substantially flush with the surface 17 of the base 10.

The upper end of the tubular member 15 is interiorly threaded, as at 18, to threadedly receive the lower end of a vertically extending pipe 19. The upper end of this pipe 19 is adapted to support the usual electric lamp fixture (not shown). The pipe 19 is preferably enclosed within a brass tubing 2O in the manner and for the purpose well understood the art Extending through the inner pipe 19 are the electric wires or conductors 21 the upper ends of which are suitably secured to the aforesaid electric lamp fixture and; thel lower ends of which are provided with a suitable electric connector or plug 22. These electric wires 21 are threaded through the pipe 19 and the member 15 into which the pipe is threaded at th-e place of manufacture and preliminarily to assembling the standard 11 and the base 10. At the same time that the standard 11 is equipped with the electric wires 21 the latter are provided with the electrical connector 22. In order to permit the free passage of this electric connector 22 through the opening in the top of the base of the lamp, the inner ends of the radially extending lugs 14 are spaced apart a distance sufficient to permit the ready passage therebetween of the electric plug. In order words, the effective internal diameter of the opening provided in the base r10 is greater than the overall transverse dimension of the plug 22.

In assembling the lamp stand 11 and the base 10, this being effected by the retailer or ultimate user of the lamp, the member 15 is positioned with the flange 16 thereof resting within the depressed seat for-med in the base. Suitable openings are provided in each of the lugs 14 of the base through which screws 23 are projected for threaded engagement with the base element 15 of the vertically extending standard or pedestal 11. In soine instances the openings which are formed in the lugs or bosses 14 through which the screws 23 project are truly circular in form as indicated by the reference numeral 24 in Figure 3, whereas in other instances these openings may be in the form of open-ended slots, as indicated by the reference numeral 25 in Figure 8. TvVhether the openings 24 or the slots 25 are employed, they are prefer-ably larger in size than the shank of the screws 23 so as to permit a certain degree of radial adjustment between the base member 15 of the pedestal and the base 10 and thereby effect proper centering of the former with respect to the latter.

In order to insure proper positionnient of the member 15 relatively to its base 10 and to relieve the screws 23 of any strain due to relative rotation of the part-s, the flange 16 of the member 15. may be provided with a'downwardlyA Iextending flange 26, portions of which are cut eut to provide a series of shoulders or abutments 27 respectively arranged to either side of each of the radially extending lugs or bosses 14'.y

Figure 4 illustrates a modified form of construction wherein the base 10 of the lamp is provided with a substantially continuous annular flange 28 in place of' the plurality of radially extending lugs or bosses 14. This flange 28 defines a central opening 29 in the top of the base 10 and forms the bottom of a depressed seat for the basemember 15 of the vertically extending standard or pedestal 11. Provided in this flange adjacent the inner .peripheral edge thereof are a plurality of openings through which the securing screws 30 may be projected for threaded engagement with the base member 15, exactly as described in connection with thel structure of Figure 1. These openings through which the screws 30 are projected may be in the form of radially extending slots such as are indicated by the reference numeral 31 of Figure t or arcuately formed elongated slots such as are indicated by the reference numeral 32.

In constructing the lamp, it will be understood that the pedestal or standard 11, including the pipe 19, the tubular member 2O and the base member 15, is constructed in its entirety and completely wired independently of the base member 10 of the lamp. To assemble the lamp it is merely necessary to` mount the base member 15 of the lamp pedestal within the seat provided therefor in the base 10 of the lamp, the parts 15 and 10 being rigidly secured together by means of thev screws 21, it being understood that the electric plug 22 is first threaded through the central opening or aperture of the base 10. Inasmuch as the screws 23 are inserted through the bottom end of the lamp structure they are not visible when the lamp is viewed in its ordinary upright position and due to the fact that the member 15 more or less snugly lits within the seat provided therefor Within the base 10 the external aspect of the lamp is that of one wherein the base and vertically eX- tending standard or pedestal are constructed integrally.

It will be understood of course that the invention is susceptible of various changes and modifications without departing from the real spirit or general principles of the invention and it is accordingly intended to claim the same broadly, as Well as specifically, as indicated in the appended claims.
